The Algae Products Market was valued at $3.28 billion in 2023 and is projected to grow to $6.01 billion by 2031, with an estimated value of $3.53 billion in 2024. This growth represents a compound annual growth rate (CAGR) of 7.9% during the forecast period from 2024 to 2031.
Algae products encompass a wide range of photosynthetic organisms found in both marine and freshwater environments, with applications across various industries. A significant trend influencing this market is the increasing demand for alternative protein sources, with algae emerging as a sustainable option that contributes to a more resilient food system.
Key types of algae-derived products include hydrocolloids, carotenoids, lipids, and algae protein, which are extensively utilized in sectors such as food and beverages, nutraceuticals, cosmetics, and animal feed. Common algae extracts originate from species like seaweed, chlorella, spirulina, Dunaliella salina, and Haematococcus pluvialis.
Hydrocolloids are particularly valuable in food, beverages, pharmaceuticals, and cosmetics, serving as functional ingredients that enhance texture, consistency, and shelf life. Their popularity is growing, especially in probiotic and zero-calorie foods, driven by consumer demand for healthier and more nutritious options.
Carotenoids, which are natural pigments found in algae, are increasingly sought after in cosmetics due to the rising preference for products based on natural ingredients. These compounds provide antioxidant, anti-inflammatory, and photoprotective benefits, making them essential in formulations designed to enhance skin health and protection. Carotenoids are commonly incorporated into sunscreens, anti-aging products, and skin repair treatments.
Algae proteins, particularly those derived from microalgae, are gaining attention for their high nutritional value and bioactive properties. Spirulina, a well-known microalga, is becoming popular as a food ingredient due to its rich content of proteins, polyunsaturated fatty acids, pigments, and vitamins.

Rising Demand for Natural Food Colors Drives Algae Product Use
The growing health consciousness among consumers and their preference for eco-friendly products are fueling global demand for natural foods. Algae have emerged as a significant source of natural food colors, offering a sustainable alternative to synthetic dyes. Plant-based food colors not only enhance the visual appeal of food products but also boost their nutritional value, avoiding the negative effects associated with synthetic additives.
Food manufacturers are increasingly using natural food colors to meet the rising demand for products made with natural ingredients. These colors can help restore the visual appeal of processed food and beverages. In the U.S., the FDA has banned certain artificial color additives linked to cancer, further accelerating the shift toward natural alternatives.
Spirulina, with its striking blue-green color, is widely used in confectionery and chewing gums. The U.S. FDA has approved spirulina extract as a natural blue coloring agent for food and beverage applications, marking it as the first natural blue food color to receive such approval. This has spurred a growing demand for spirulina-based colors in beverages, dairy products, and confections. Other food categories, such as frostings, ice creams, dry beverage mixes, yogurt, and gelatin, also utilize spirulina extract as a natural blue colorant. From 2014 to 2020, the volume of spirulina used in food and beverage applications increased fivefold, contributing to an average annual growth rate of 6.8% for the natural food coloring industry.
Astaxanthin, another natural pigment derived from Haematococcus pluvialis microalgae, is experiencing increased demand in the food sector. While some manufacturers use synthetic astaxanthin, concerns over its safety for direct human consumption have led to a preference for natural astaxanthin, especially in premium markets. Astaxanthin from Haematococcus pluvialis is approved as a color additive for salmon feed and as an ingredient in dietary supplements in various countries, including the U.S., Japan, and parts of Europe. This natural pigment is commonly used to impart a red-orange color to seafood, meat, poultry, dairy, and bakery products.
